What is IP65 and IP67 EV Charger & Why It Matters in Indian Conditions?
When evaluating an EV charger, most buyers focus on power output, voltage compatibility, and certifications. IP rating like IP67 EV charger rarely comes up — until a charger fails in the middle of monsoon season, or a dusty depot environment starts causing faults after three months of use.
For anyone sourcing a charger for an IP rating EV charger India deployment, understanding this specification is non-negotiable. A waterproof EV charger is not just a feature — in Indian conditions, it is a baseline requirement.
In India, where chargers are deployed across open parking lots, roadside charging points, warehouse floors, and flood-prone areas, the IP rating of your charger is not a secondary specification. It is a primary one.
Let’s learn about IP65 & IP67 and how they are different from each other. We will also learn about which rating is suitable best as per your application needs.
What Is an IP Rating?
IP stands for Ingress Protection. It is an international standard defined under IEC 60529 that classifies how well an electrical enclosure resists the entry of solid particles and liquids. As seen, IP rating generally includes two digits. The first of these two digits is related to protection against dust and solid particles while the other one is related to water protection.
One can say, the higher the number in rating, better or stronger is the protection against the same. When discussing deployment of EV chargers in the real-world environment, the most relevant ratings are IP65 and 67.
Breaking Down IP65 EV Charger
The first digit 6 means the enclosure is completely dust-tight. No dust or solid particles can enter under any conditions. This is the maximum level of solid particle protection available under the IP standard.
The second digit 5 means the enclosure can withstand water projected from a nozzle in any direction. This covers rain, splashing, and jet washing — but not submersion.
Charger with IP65 rating is ideal for installation outdoors that are semi-exposed or somewhat sheltered. This environment generally involves water coming from rain or splashing and not floods or standing waters.
Breaking Down IP67 EV Charger
The first digit 6 is identical to IP65. Completely dust-tight.
The second digital in the rating, that is 7, here means that the enclosure is prepared to withstand water immersion (temporarily) up to one meter depth for half an hour (30 minutes). This is where IP67 rating covers the scenarios where the charger or the EV is exposed to conditions like pooling, flooding or standing water.
This means that a charger with IP67 rating is designed for environments that are exposed to outdoors like flood-prone areas. It is also relevant to applications where the charger somehow is in some direct and sustained contact with water.
IP65 vs IP67 EV Charger — The Key Difference
The practical difference between an IP65 vs IP67 charger comes down to one scenario: submersion.
Both ratings offer complete dust protection and protection against water jets and rain. IP67 ratings help in surviving immersions on a temporary basis where water is accumulating at the ground level or flooding is quite often in the region.
IP65 rated chargers, on the other hand, can survive outdoor installations that has proper drainage systems and mounting heights.
Why IP Rating Matters for EV Charger India Deployments
India presents a set of environmental challenges that make IP rating one of the most important specifications for any outdoor EV charger deployed in this market.
Monsoon conditions: In the monsoon season, many states and regions of India experience heavy rainfall, waterlogging and street flooding scenarios. A charger rated below IP65 in these environments is at serious risk. A monsoon proof EV charger needs at minimum IP65 — and IP67 for ground-level or flood-prone deployments.
Dust and particulate matter: In industrial areas, construction zones, unpaved depot yards, and dry northern regions, airborne dust is a constant challenge. A dustproof EV charger India deployment requires the first digit to be 6 — anything less allows particulate matter to enter the enclosure over time, degrading internal components.
Heat and humidity: Coastal areas in India often experience humidity and salt air that results in corrosion in sealed enclosures. An IP-rated enclosure with a sealed die-cast aluminium shell — like those used across the Solterra certified and portable charger ranges — provides a meaningful barrier against this degradation.
Depot and warehouse environments: Fleet depot charging often takes place in the area with open yards and semi-closed warehouses where occasional dust, water exposure are seen. An IP65 rated charger is typically a correct choice in such charging stations. But in the region where charging stations are installed in open-yards, an IP67 rated charger is a better choice.
When to Choose IP65 and When to Choose IP67?
Choose IP65 when:
- The charger is mounted at height (wall, post, or bracket-mounted)
- The installation is sheltered or semi-covered
- Water exposure comes from rain and splashing only
- The environment is dusty but not subject to flooding
- Application: covered depot yards, indoor warehouse charging, semi-outdoor 2W/3W charging points
Choose IP67 when:
- The charger is ground-mounted or at low height
- The charging installation is in a region prone to floods or waterlogging
- The charger may be exposed to standing water
- The application involves coastal or high-humidity environments
- Application: open outdoor charging points, roadside installations, monsoon-prone regions, coastal fleet depots
What Happens If You Use the Wrong IP Rating
Using a charger with insufficient IP protection in an exposed environment does not cause immediate failure. It causes gradual degradation — moisture entering the enclosure over weeks or months, dust accumulating on internal components, corrosion forming on connections. By the time a default in the charger is noticed by a user, the damage has already been spread for sometime now.
This results in reduced charging efficiency and increased frequency in the fault, which means premature replacement of the charger. For OEMs and fleet operators, this adds up to a huge cost of maintenance and unplanned downtime of the vehicle, impacting direct revenue.
Solterra’s Approach to IP Protection
Across the Solterra portable and certified charger range, IP65 sealing is standard. Every charger ships with a die-cast aluminium enclosure fully potted with soft silicon — providing both structural durability and reliable ingress protection against dust and water in the environments where Indian fleets and OEMs actually operate.
For high-power on-board charger applications requiring IP67, the Solterra ST-C Series on-board chargers carry IP67 certification — suitable for vehicle-mounted deployments where the charger may face more extreme environmental exposure.
Choosing the right IP rating before procurement is simpler than replacing equipment after it fails. Match the rating to the environment, and your charging infrastructure will last as long as it should.
